The purpose of this evaluation of the children's book review centers was to determine the answers to two major questions: Would the children's book review centers(CBRC) receive enough use to justify their continued funding and existence? and would the CBRCs improve the librarians' selections of children's books? Data for the study were collected through the use of (1) a monthly report containing lists of the number of books received that month and the number of persons signing the visitor's registrat, and a photocopy of the register; (2) a questionnaire sent to the school and public librarians who had signed the register one or more times and to public librarians responsible for children's book selection who had not signed the register; and (3) a questionnaire and a site visit to the 53 school and public librarians involved in the study. The conclusion based on the data was that the children's book review centers cannot be viewed as successful. The children's librarians who first requested the CBRCs showed the least benefit. The selection of recommended books by school librarians and heads of public libraries improved, but more books not recommended were also selected. (WR)
